Water server

Abstract

Provided is a water server that makes it possible to prevent water leaks, that is inexpensive, and that has excellent sanitary properties. The water server has a configuration that comprises: a cold water tank (2); a first water level sensor (3) that detects the water level within the cold water tank (2); a cold water tank supply pipe (4) that guides drinking water to the cold water tank (2) when the water level detected by the first water level sensor (3) decreases; a buffer tank (6); a second water level sensor (7) that detects the water level within the buffer tank (6); a buffer tank water supply pipe (8) that guides drinking water to the buffer tank (6) when the water level detected by the second water level sensor (7) decreases; an atmosphere connection path (27) that is provided to the cold water tank (2) in order to maintain the cold water tank (2) at atmospheric pressure; an air flow pipe (36) that connects the air layer of the cold water tank (2) with the air layer of the buffer tank (6); and an abnormal water level sensor (34) that detects when the water level within the cold water tank (2) has reached an abnormal water level.

Description

technical field [0001] The present invention relates to a water dispenser for supplying drinking water from a replaceable raw water container filled with drinking water such as mineral water. Background technique [0002] In the past, water dispensers were mainly used in offices, hospitals, etc., but in recent years, water dispensers have become popular in ordinary households due to increased concerns about water safety and health. As such a water dispenser, there is generally known a water dispenser in which a replaceable raw water container is placed on the upper surface of a frame, and the drinking water filled in the raw water container falls by gravity to a cold water tank accommodated in the frame ( For example, refer to the following patent document 1). [0003] In the water dispenser of Patent Document 1, since the raw water container is placed on the upper surface of the frame, when the raw water container is replaced, the full water container needs to be lifted hi...

Problems solved by technology

[0012] However, in this case, the number of water level sensors increases, which increases the manufacturing cost of the water dispenser.

In addition, each of the cold water tank 61 and the buffer tank 63 is provided with an opening for communicating with the atmosphere, so there is a high possibility that bacteria enter the tank from the atmosphere, making it difficult to ensure hygiene.
